Posted · Add Comment

When planning your fishing trip to Alaska, one of the biggest decisions you’ll make is where to fish. Two of the most productive and scenic rivers in the state—the Kenai River and the Kasilof River—are both located on the Kenai Peninsula and offer unforgettable experiences for anglers of all skill levels.

At Kenai Fly Fish, we guide trips on both rivers, and each one offers its own unique adventure. Whether you’re a first-timer, a family, or a seasoned salmon hunter, here’s how to choose between the Kenai vs. Kasilof for your next Alaska fishing trip.


📍 The Basics – Location & Access

Kenai River:

  • The most famous river in Alaska

  • Runs 82 miles from Kenai Lake to Cook Inlet

  • Easily accessed from towns like Soldotna, Kenai, and Cooper Landing

  • Power boats allowed in many sections

Kasilof River:

  • Just 12 miles south of the Kenai River

  • Flows from Tustumena Lake to Cook Inlet

  • Motor-free drift boat only river

  • More secluded, quieter, and less pressured

Both rivers are less than 30 minutes apart, so it’s easy to fish both during your stay—but choosing the right one for your primary trip can shape your experience.


🎣 Fishing Style & Trip Vibe

Kenai River – Power Boat Access, Big Water, Big Fish

  • Great for covering a lot of river quickly

  • Ideal for combo days (salmon + trout)

  • Active, fast-paced fishing

  • More fishing pressure and boat traffic during peak season

  • Perfect for anglers who want action and variety

Kasilof River – Drift Boat Only, Peaceful & Intimate

  • Motorless = quiet, relaxing, and scenic
